# Verification record — is/utl/other-residence-permit-application@1.0.0 ## Candidate selection Iceland (`IS`) had 2 of 6 verticals modelled before this cycle (`is/skatturinn/business-employer-vat-registration`, `is/skatturinn/simplified-individual-tax-return`: Business Formation and Taxes). Its Visa vertical had a known, previously-scouted-but-unauthored candidate: Form **D-110**, "Other Residence Permits" (Umsókn um dvalarleyfi — annað), published by Útlendingastofnun (the Directorate of Immigration, ÚTL). This document authors that candidate, opening Iceland's Visa vertical (3rd of 6). D-110 is the Directorate's catch-all/generic residence-permit application: its own cover page states "The form is for adult individuals who are applying for a residence permit for which there is no separate application form." Unlike this registry's `jp/isa/certificate-of-eligibility-application` precedent (which sits atop dozens of category-specific supplements), D-110 is a single bounded 9-page, 13-numbered-section document, so the whole form is modelled here, not just a cover sheet. ## Source and the two-URL byte-diff finding - **Primary source (used for this schema):** `https://assets.ctfassets.net/8k0h54kbe6bj/16DdpHCIa2fJPorxM5DAaC/f111b805dae2f57dd2acc62c543f7224/D-110-onnur-dvalarleyfi-EN.pdf` — fetched fresh via `curl` on 2026-07-10: HTTP 200, `content-type: application/pdf`, exactly **407,240 bytes** (SHA-256 `46a68da0adbfbeee73ad573bc14a63e812e3d21c7fd6a98789a7e3400f998e9f`). `Last-Modified: Tue, 12 Dec 2023 14:12:42 GMT`. - **Second URL surfaced in search, same filename, different Contentful asset ID:** `https://assets.ctfassets.net/8k0h54kbe6bj/28awrApHRqsbRUILpmsqIi/33a411945bf3a30f3e3aa00abded8f74/D-110-onnur-dvalarleyfi-EN.pdf` — also fetched fresh: HTTP 200, `content-type: application/pdf`, exactly **303,063 bytes** (SHA-256 `17048918885d983977ed14903d2856f30520949145e23f1bf601d1f687442bbb`). `Last-Modified: Thu, 06 Jun 2024 15:57:40 GMT` — a *later* timestamp than the primary URL's. - These two files are **not** the same document re-hosted: a full pdfjs-dist text-content diff (normalized whitespace, page-by-page) shows the second file has a genuinely different section structure — a **14th numbered section** ("2. Ties with Iceland or other Schengen countries") inserted between what the primary source calls sections 1 and 2, shifting every subsequent section number by one (the primary source's section 12 "Checklist" is the second file's section 13; section 13 "Date and signature" becomes section 14), and different sub-section ordering (the second file's section 4 is "Applicant's spouse", where the primary source's section 4 is "Applicant's spouse" too but its section 5 is "Applicant's children" — the second file interleaves parents/relatives differently). It also has a different widget count: **256 widgets** (5 more than the primary's 251) via the same pdfjs-dist `getAnnotations()` re-extraction. - **Resolution: the primary URL (16Ddp…) is treated as the current, correct source; the second URL (28awr…) is treated as a stale/superseded intermediate CDN artifact.** Evidence for this call: 1. A live web search independently surfaced a *third*, most-recent file at the **same asset ID** as the second URL (`28awrApHRqsbRUILpmsqIi`) but a *different* content hash (`789b50e2f33624271b9af2d98b79ead1`) and a filename with **no `-EN` suffix** (`D-110-onnur-dvalarleyfi.pdf`) — i.e. an Icelandic-language file. Contentful asset IDs are content slots that get their file replaced on re-upload while old content-hash URLs remain live on S3/CloudFront indefinitely (confirmed both hash URLs still return HTTP 200 today). This means the asset slot behind the second URL has since been overwritten at least once more, with a non-English file — consistent with that slot having held a transitional/incorrect English draft in mid-2024 that was later corrected, rather than being the actively-maintained English asset. 2. The primary URL's content matches this issue's own authoritative 13-section outline (as given in the task brief, itself derived from a prior scouting pass of this exact candidate) **exactly** — same section count, same section 12/13 boundary (Checklist / Date and signature). The second URL's 14-section structure does not. 3. The primary URL's asset ID has shown no further replacement (no other hash has been found at that slot), consistent with it being the stable, currently-canonical asset. - This is disclosed as a real, resolved discrepancy rather than silently picking one file: a reviewer who wants to re-derive this call can repeat the `curl -sI` HEAD requests and the web search above. - **Authority page:** `https://island.is/s/utlendingastofnun` — confirmed live (HTTP 200) as Útlendingastofnun's current island.is-hosted landing page; the legacy `utl.is` domain (referenced inside the PDF's own boilerplate footer, `utl@utl.is | www.utl.is`) has been folded into island.is under the whole-of-government migration, consistent with this registry's other recently-authored Icelandic-authority schemas. ## Extraction technique and re-verification of the prior session's numbers A prior pass in this same session had already extracted the primary PDF with `pdfjs-dist` (Node, no `canvas` polyfill), saving widget/text dumps to `/tmp/pdfextract/`. Per this registry's own convention ("own re-extraction, not trusting a prior pass"), this cycle re-did the fetch and extraction completely from scratch in a separate scratch directory (`/tmp/is-utl-verify/`), confirming: - Fresh `curl` fetch: 407,240 bytes, SHA-256-identical to the prior pass's local copy (`cmp` byte-for-byte match). - Fresh `pdfjs-dist` `getAnnotations()` pass, page by page: **251 AcroForm widgets across 9 pages**, matching the prior pass's dump (`/tmp/pdfextract/widgets.txt`) exactly via a plain-text `diff` (no differences). - One genuine anomaly confirmed in both extractions: two AcroForm text-field widgets, `Text Field 6` and `Text Field 214` (page 2, "Given name"), occupy an **identical rectangle** — `[163.075, 638.3–658.5, 566.929]` in both passes. This is a duplicate/orphaned widget left behind by a form-editing artifact (e.g. a field replaced in place without deleting the original). Modelled as a single field (`givenName`) since the two widgets are visually indistinguishable as one line on the rendered page; disclosed in the field's own `description`. Field names and labels were derived with a **position-aware (x/y proximity) mapping script**, not manual eyeballing of the widget dump against the text dump — the same technique this registry's `at/bmeia/schengen-visa-application` and `se/migrationsverket/work-permit-application` schemas' own VERIFICATION.md records describe using. For every widget, the script pulled `getTextContent()` items within roughly the same y-band to the *left* of the widget (candidate inline label) and within 20pt *above* the widget (candidate section/column header), then a human pass resolved the final field identity from that evidence plus the source's own running prose. This caught and corrected an initial manual (text-order-only) misreading of the page-1 residence-permit category checkboxes: reading the six category checkboxes as column-major (all of the left column, then all of the right column) produces the wrong pairing; the position-aware evidence (each row's between-checkbox label text belongs to that row's *left* checkbox, with the *right* checkbox holding the next phrase in the source's own running list) shows the true order is row-major — `Working Holiday/Youth Mobility`, `for volunteers` (row 1), `for missionaries`, `on grounds of legitimate and special purpose` (row 2), `based on special ties to Iceland`, `Other, what?` (row 3). The same row-major rule, cross-checked against the page-2 gender/marital-status grid (which the position-aware evidence and the source's own running text agree on independently), is used throughout this document wherever a form-numbered option grid needed disambiguating (education level, field of study, the 6×5 children gender/is-in-Iceland grid, parent gender). ## Field count and modelling decisions **185 fields, 9 `documents[]` entries, 14 `steps`, 6 `crossFieldValidation` rules, 0 `exclusivityGroups`.** ### Repeating-row bounds Three sections have repeating rows; each is bounded to the number of rows the source PDF itself visibly provides (this registry's established convention, e.g. `se/migrationsverket/work-permit-application`'s `previousStay1..4`, `child1..5`), not padded or extended: - **Section 3, residence abroad** — 6 rows (`residenceAbroad1Country` … `residenceAbroad6DateTo`), confirmed via the widget grid (18 widgets, 6 rows × 3 columns: country / date-from / date-to). - **Section 5, children under 18** — 6 rows × 6 fields each (given name, surname, ID number/date of birth, citizenship, gender, is-in-Iceland), confirmed via a 5-column × 6-row checkbox grid (gender: Boy/Girl/Non binary-other; is-in-Iceland: Yes/No) plus a 4-column × 6-row text grid. - **Section 7, relatives in Iceland** — 6 rows × 4 fields (given name and surname combined into a single field — the source table gives given name and surname one shared, double-width column rather than two separate columns, unlike the children table — date of birth, citizenship, kinship). ### `requiredWhen` gates ("I do not have X" pattern) Three sections are gated by a boolean "I do not have X" / "I have no X" checkbox: spouse (`hasNoSpouse`), children (`hasNoChildrenUnder18`), relatives (`hasNoRelativesInIceland`). Detail fields in each section carry `requiredWhen: { field: "", equals: false }` — a boolean-equality check, not the `notEquals: ""` pattern this registry's memory flags as a bug (gating an optional field's requiredness on `notEquals` an empty string silently mis-fires when the referenced field is simply absent). The same boolean-equality gate pattern is used for every other "detail fields only apply when the gating Yes/No answer is X" relationship in this document (e.g. `wasFinedOrImprisoned`, `subjectedToReEntryBan`, `banStillInEffect`, `residencePermitCategory: "other"`, `whoFilledOutApplication: "other"`). ### Genuine Yes/No question pairs modelled as a single boolean Every place the source form prints two separate checkbox widgets for a single Yes/No question (e.g. "Are both or one of your parents Icelandic citizens? Yes / No", "Have you previously applied for a residence permit in Iceland? Yes / No", the three criminal-record Yes/No questions) is modelled as **one boolean field**, not two independent booleans — matching `at/bmeia`'s (`residesInOtherCountry`) and `se/migrationsverket`'s (`previouslyAppliedToComeToSweden`, `requestRevokeCurrentResidencePermit`) own established pattern for exactly this case. ### Divergence from a literal `exclusivityGroups` reading — flag for reviewer The task brief for this cycle suggested modelling every true single-select checkbox grid (gender, marital status, the 6 residence-permit categories, the two Y/N pairs) with `exclusivityGroups` (GSP-0013). **This document does not use `exclusivityGroups` at all**, after checking what `at/bmeia` and `se/migrationsverket` actually do for the equivalent cases in their own source forms, per the brief's own instruction to "follow suit": both of those schemas model a true single-select-among-named-values grid as a single `type: "enum"` field (e.g. `at/bmeia`'s `sex`, `maritalStatus`, `travelDocumentType`, `mainPurposeOfJourney`; `se/migrationsverket`'s `applicationCategory`, `healthCoverageBasis`, `requestRevokeCurrentResidencePermit`) — reserving `exclusivityGroups` for one specific different case: `at/bmeia`'s `costOfTravelFundedBySelection`, where the four "who funds the trip" checkboxes are each independently *named* and referenced elsewhere (two of the four carry their own distinct conditional description sub-field), and the mutual exclusivity is a cross-field business rule layered on top of otherwise-independent booleans — not a case of one value being selected from a closed list. Every true single-select grid in D-110 (gender, marital status, application type, residence-permit category, children's gender, parents' gender, field of study, who-filled-out-the-application, preferred contact method) fits the `enum` shape cleanly — a fixed list of named values, no per-option sub-field structure beyond a single common "other, please specify" follow-up (handled with a plain `requiredWhen` on the free-text field, as `at/bmeia` and `se/migrationsverket` already do for their own "other" options). `exclusivityGroups` is reserved by spec for `boolean`-typed fields only (§8.4), and this document has one candidate that arguably fits its *intended* independently-named-booleans shape: the 8 education-level checkboxes in section 8. Those are, however, explicitly a **multi-select** in the source ("check all the applicable boxes") — not mutually exclusive at all — so `exclusivityGroups` would be actively wrong there; they are modelled as 8 independent optional booleans, each with its own optional `requiredWhen`-gated graduation-year field, mirroring `at/bmeia`'s `fundedBy*`/means-of-support pattern for independent, individually-relevant booleans, without asserting exclusivity. **Reviewer should double-check:** whether this divergence from the brief's literal suggestion is the right call, versus force-fitting `exclusivityGroups` onto one or more of the above enum fields to match the brief's example list verbatim. ### The paraphrased consent/declaration block Page 9's pre-signature declaration (data-processing consent, the Directorate's authority to obtain information from other domestic/foreign bodies, the medical-examination condition, and the accuracy declaration) is paraphrased into a single `documents[]` `attestation` entry (`applicantSignatureDeclaration`), not quoted verbatim or split into per-statement checkboxes — the source presents it as one continuous prose block ahead of a single "Applicant's signature" line, with no per-statement checkbox of its own, matching `at/bmeia`'s own disclosed treatment of its equivalent declaration paragraph. ### The "Other, what?" free-text category `residencePermitCategory` is a 6-value `enum` (`working_holiday_youth_mobility`, `volunteer`, `missionary`, `legitimate_special_purpose`, `special_ties_iceland`, `other`); `otherCategoryDescription` is `requiredWhen: { field: "residencePermitCategory", equals: "other" }`, matching the cover page's own instruction: "If 'Other, what?' is selected, it must be specified on what other basis the application is made." ### Checklist as `documents[]` The 8 supporting-document checkboxes in section 12 ("Did you remember everything?") are modelled as `documents[]` entries (this registry's established convention for attestation/checklist blocks), not invented per-item required fields: | Document | Category | Required | |---|---|---| | Payment receipt | supporting-evidence | yes | | Passport photo | identity-document | yes | | Copy of passport | identity-document | yes | | Copy of criminal record certificate | supporting-evidence | yes (freshness: within 12 months) | | Translation of criminal record certificate | supporting-evidence | no (only if not English/Nordic) | | Health insurance confirmation | supporting-evidence | yes | | Documents confirming secure financial support | supporting-evidence | yes | | Special data requirements (category-specific) | supporting-evidence | no | A 9th checklist checkbox, "Applicant has signed the application," is modelled as a plain boolean field (`checklistApplicantHasSigned`) rather than a `documents[]` entry, since it is a self-check confirming a fact about the same form (not a supporting document); the actual signature/declaration is separately modelled as the `applicantSignatureDeclaration` attestation above. ### `crossFieldValidation` Six rules, one per residence-abroad row, each requiring that row's `DateTo >= DateFrom` — the only genuinely comparable date pair in this document (the criminal-record ban dates and the intended/actual Iceland-arrival dates are not both always present in the same scenario, so no cross-field rule was invented for them). ## Mock conformance test run Two scenarios and eight mutation/negative controls were built and checked against this schema's own `required`/`requiredWhen`/`visibleWhen`/ `validation`/`documents[]`/`crossFieldValidation` grammar with a disposable checker script (`/tmp/is-utl-verify/check_conformance.mjs`, not committed — same technique as `at/bmeia/schengen-visa-application`'s own `check_conformance.mjs`, extended to also evaluate `crossFieldValidation`'s `compare` shape): - **`scenario1-full-coverage-other-category.json`**: a maximal-coverage applicant selecting the "Other, what?" residence-permit category (with a description), who has a spouse, 6 children, and 6 relatives in Iceland fully filled in, has already arrived in Iceland, has been in Iceland before, answers "yes" to all three criminal-record questions (with every conditional detail field populated) and has an active re-entry ban, and has someone other than the applicant/agent fill out the form. **All 185 fields collected, 0 not-applicable, 0 errors**; all 9 `documents[]` entries provided. - **`scenario2-minimal-branch.json`**: the opposite branch — a special-ties-to-Iceland applicant with no spouse, no children under 18, no relatives in Iceland, who has not yet arrived and has never been to Iceland before, answers "no" to all three criminal-record questions, has not yet decided on an Iceland address, and fills out the form themself. **92 fields collected, 93 correctly not-applicable (spouse/children/ relatives detail fields, the "other" free-text fields, the criminal-record and re-entry-ban detail fields, the not-yet-known Iceland address fields), 0 errors**; only the required `documents[]` entries provided (the two optional ones, translation and special data requirements, correctly omitted). - **Eight mutation/negative controls**, each derived from scenario 1 with exactly one defect introduced, each correctly raising exactly one error: 1. Removing the required `surname` → `missing-required`. 2. Setting `gender` to `"unspecified"` (not in its 3-option `enum`) → `enum-violation`. 3. Setting `agentSecurityNumber` to `"12"` (violates the 4-digit `^[0-9]{4}$` pattern) → `pattern-violation`. 4. Removing `otherCategoryDescription` while `residencePermitCategory` stays `"other"` → `missing-required` (`requiredWhen` conditional- required violation). 5. Removing `spouseGivenName` while `hasNoSpouse` stays `false` → `missing-required` (`requiredWhen` conditional-required violation). 6. Setting `residenceAbroad1DateFrom` to `2015-01-01` and `residenceAbroad1DateTo` to `2014-01-01` (departure before arrival) → `cross-field-violation` on `residenceAbroad1DateToNotBeforeDateFrom` — confirming `crossFieldValidation` actually fires. 7. Removing the required `passportPhoto` document → `missing-required-document`. 8. Removing `banStillInEffect` while `subjectedToReEntryBan` stays `true` → `missing-required` (`requiredWhen` conditional-required violation). The schema was also validated against the GovSchema v0.3 meta-schema with `node tools/validate.mjs` and `node tools/validate-ajv.mjs` (both pass, individually and as part of the full 339-document registry run — 338 pre-existing + this one, no other document affected), and against `node tools/verify-sources.mjs registry/is/utl/other-residence-permit-application/1.0.0` (1 directory, 3 URLs checked, 0 warnings, 0 allowlisted, all clear). ## Pre-PR re-verification Both candidate PDF URLs and the authority URL were fetched live a final time immediately before finalizing this record, using `curl -sI` HEAD requests, confirming the byte counts, content hashes, and `Last-Modified` timestamps recorded above are stable and reproducible.
